with temperatures below–20°C (–4°F) or above +55°C (+131°F).
DO NOT
modify the transceiver. The specifications may change
and then not comply with the requirements of a corresponded
regulation. The transceiver warranty does not cover any problems
caused by unauthorized modification.
DO NOT
use harsh solvents such as benzine or alcohol when
cleaning, as they will damage the transceiver surfaces.
BE CAREFUL!
The transceiver will become hot when operating
it continuously for long periods of time.
BE CAREFUL!
The transceiver meets IP67 requirements for
dust-tight and waterproof protection.
However, once the transceiver has been dropped, dust-tight and
waterproof protection cannot be guaranteed because of possible
damage to the transceiver's case or the waterproof seal.
Even when the transceiver power is OFF, a slight current still flows
in the circuits. Remove the battery pack or batteries from the trans-
ceiver when not using it for a long time. Otherwise, the installed
battery pack or batteries will become exhausted, and will need to
be recharged or replaced.
MAKE SURE
to turn the transceiver power OFF before connect-
ing the supplied/optional equipment.
